The programming world lost a very intelligent and caring contributor today who exemplified the hacker spirit. I never had the opportunity to interact with him directly, but read plenty that he wrote. By all accounts that I have ever heard, he was always willing to share his knowledge with newcomers and experienced developers alike. RIP Joe Armstrong.
